The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks.
We’ve got a bit of a slow start, but once it gets going, there’s some real fun to be had. The first wave of the period rolls in on Monday the 27th of July, and it’s a solid little pulse. The standout early on is Jaconé – a consistent, exposed setup that’s an intermediate dream. The water’s sittin’ at a lovely 72°, which is bang on average for the time of year, so no surprises there.
Monday morning the 27th, we’re looking at a clean 3 ft of south swell, with a 12-second period – that’s proper groundswell, nice and lined up. The wind is light offshore from the NE at 6 mph, so the face will be like glass. Combined swell energy is a solid moderate 389, and it’s got that optimum SE direction lockin’ in. This is the pick of the bunch. Come Monday afternoon, the wind swings and it gets a bit messy, so get out early.
Tuesday the 28th offers a smaller 2 ft south swell in the morning, still clean with that NE offshore breeze, but the energy drops to 197. It’s surfable but ordinary. Afternoon’s even smaller.
Wednesday the 29th is a similar story – 2 ft south swell, but the wind goes light and cross-off, so it’s still clean. Energy’s 184. Afternoon picks up a little energy to 256, but it’s just okay.
Thursday the 30th is a write-off – onshore wind and poor conditions. Friday the 31st brings a bit of a rebound: 4 ft of south swell, 9-second period, with a light cross-off breeze in the morning. Energy’s 290. It’s clean, but the period is a little short for that real grunt.
Now, Saturday the 1st of August – morning is a gem. 3 ft south swell, but the period is back to 12 seconds, and the wind is offshore from the NE at 12 mph. That’s clean, with moderate energy at 299. The afternoon gets blown out with a fresh 19 mph cross-off, so don’t bother.
Sunday the 2nd of August is different. The swell shifts to the east at 4 ft, but the period is a short 7 seconds. It’s still clean with a light offshore NNE breeze, and the energy is 280. It’s rideable, but that short period means it’ll be a bit soft and lumpy. Best for the longboard or a fun fish.
Monday the 3rd of August sees a drop to 3 ft east swell, still 7-second period, but the morning offshore from the NE at 3 mph is glassy. Low energy at 209. Afternoon gets a cross-shore, no good.
From Tuesday the 4th through to Thursday the 6th, it’s a mixed bag. Tuesday morning is tiny at 2 ft, and the energy is a weak 70. Wednesday the 5th of August though - that’s a sneak peek. Morning brings 4 ft of south swell, 11-second period, and a moderate offshore from the NE at 12 mph. Energy is a solid 379. That’s a good morning session, but the afternoon gets ruined by a fresh breeze. Thursday the 6th stays clean all day with a 3 ft south swell, 10-second period, and gentle offshore in the morning.
Friday the 7th of August is a no-go – onshore wind and poor conditions. Saturday the 8th of August is tiny again, 2 ft, but Sunday the 9th of August morning is a real standout. We’ve got 5 ft from the ENE, 8-second period, and a gentle offshore from the NE at 9 mph. Energy is 335. That’s a fun, punchy little wave, but it’s a bit short-period. The afternoon goes weird with a cross-off and a 5 ft southwest swell but only 5 seconds – that’s just messy.
From Monday the 10th of August onward, it gets ugly. Onshore winds, rain, and poor conditions dominate. The swell on Tuesday the 11th of August is a big 4 ft from the SSW with a 12-second period, and the energy is a massive 604, but it’s all onshore wind and choppy. That’s a kite-surfing day, not a paddle day.
So, what’s the best on offer? That Monday morning the 27th of July is the clear winner – clean, light offshore, decent groundswell. And keep an eye on Sunday the 9th of August morning – it’s a bit further out, so less certain, but if the wind holds, it’ll be a fun one.
Rusty.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
